First of all, I can't boot my Windows 7. I get a black screen with a cursor up in the left corner.
So, I tried using Windows 7 installation which I've put on my flash drive. To boot from the drive, I've changed the boot order to boot from the drive first. It boots but does not find any HDD to install Windows on (which is pretty logical, I don't boot the HDD soon enough for the installer).
But if I put the HDD in front of the flash drive in the boot order, it will just try to load Windows 7 and I will get the black screen again. I've tried putting the HDD first and clicking F8 a lot. All I've got is an error. Something about some software change. I don't know.
Help me please, I can't do anything with my laptop until then.
